Silver Spring Campus Expansion

United Therapeutics has reached an agreement with Montgomery County to acquire the County-owned parking garage known as Public Parking Garage No. 2 at 8700 Cameron Street. The acquisition of the property further expands United Therapeutics’ footprint in downtown Silver Spring and represents United Therapeutics’ long-term commitment to Montgomery County. United Therapeutics employs more than 225 full-time employees in downtown Silver Spring and contributes significantly to Montgomery County and the State of Maryland’s bio-health economy and ecosystem.

The current agreement with the County applies only to acquisition of the parking garage, including construction of the replacement parking, relocation of the parking operations facility and new fiber hub. Any future use for the property by United Therapeutics will be subject to the County’s regulatory approval process.

See details about the expansion project below.

Spring Street Parking Garage

The acquisition of the Silver Spring parking garage will allow United Therapeutics to continue to advance life-saving research and discovery at its urban campus and co-headquarters in downtown Silver Spring. 

There are no immediate plans to develop, and future use will be subject to the County’s regulatory approval process. Under the agreement, United Therapeutics has 10 years to redevelop 8700 Cameron Street with a minimum investment of $50M. United Therapeutics will construct replacement parking at a cost equal to or exceeding fair market value of the existing garage. 

The County will continue to own and operate the existing public parking garage until the replacement parking is completed, the new fiber hub is constructed, and the parking operations facility has been relocated. Upon completion of these conditions to the County’s satisfaction, the property at 8700 Cameron Street will be transferred to United Therapeutics.

Replacement Parking on Georgia Avenue

Replacement parking will be constructed near the corner of Colesville Road and Georgia Avenue at 8615 Georgia Avenue. The current parking garage will remain operational as a County-owned and operated parking garage until the replacement parking is completed.  

The surface lot will be purchased by United Therapeutics and transferred to the County upon completion of the new parking structure which will contain 675 parking spaces.

United Therapeutics is committed to working with the selected contractors and community to minimize the impacts of construction. The current parking garage will remain operational as a County-owned and operated parking garage until the replacement parking is completed.  

No date has been set for construction to begin and United Therapeutics is committed to keeping the public informed about the construction process and timeline. 

Parking Operations Building

The current parking operations facility will be relocated to 9150 Brookville Road and renovated according to the County’s specifications. 

The County’s parking operations unit has responsibility for the collection and the processing for deposit of all parking revenue, including revenue from individual meters, automated pay stations, cashiered facilities, parking permits, and parking fines. The unit also provides contract security guard services for parking facilities to detect and report theft, vandalism, and threats to personal security. 

The new facility will replicate the operations that currently exist in the parking operations facility and provide additional room for the County to utilize into the future.

New Fiber Hub

United Therapeutics’ acquisition of parking garage at 8700 Cameron Street provides an opportunity to construct a new, state-of-the-art fiber hub to serve the community's needs.  


The fiber hub, overdue for modernization to ensure the reliability and quality of its performance, will be located at 8904 Fairview Road, which is currently a surface parking lot owned by United Therapeutics. The property will be transferred to the County at no cost to taxpayers and the County will oversee the construction. 

With any new construction, some impact will be realized. However, the structure of the fiber hub will be modular and designed to blend into the current landscape. The 2-acre park connecting downtown Silver Spring to the Woodside community will not be impacted.
